Hi,
everything was going fine untill today.
I finished assembling a pair of A12.
When I was ajusting the voltages the main led begun to pulse.
The -30 led of the power suply was pulsing also, making a vibrating noise.
After some seconds everything stopped.
And now there is no sound and the Outside LED is almost gonne.
it stills pulsing, but almost nothing ... I almost can't tell it is on or off.
Even taking all modules out, it stills like this.
Why does this happens ? The pulsating light !
And what do you think happened with my power suply ?
thank you,
Arthur
